A plane mirror and an object has speeds of `5 m//s "and" 10 m//s` respectively. If the motion of mirror and object is along the normlal of the mirror then the speed of image may be:-

A plane mirror is placed along the y-axis such that x-axis is normal to the plane of the mirror. The reflecting surface of the mirror is towards negative x-axis. The mirror moves in positive x-direction with uniform speed of 5 m/s and a point object P is moving with constant speed 3m/s in negative x-direction. find the speed of image with respect to mirror in m/s.

An object is 20 cm away from a concave mirror with focal length 15 cm. If the object moves with a speed of 5 m/s along the axis, then the speed of the image will be

A real object is placed in front of a convex mirror (fixed).The object is moving toward the mirror. If v_(0) is the speed of object and v_(i) is the speed of image, then

A particle moves perpendicular towards a plane mirror with a constant speed of 4 cm//s .What is the speed of the image observed by an observed moving with 2 cm//s along the same direction? Mirror is also moving with a speed of 10cm//s in the opposite direction. (All speeds are with respect to ground frame of refrence)
